For il-.lstaueez in a.com.meercial,k embodiment: of' the gas Water heater aforesaid, said valve 5,

is normally maintained shut by a spring 19 exerting a pressure of about live pounds upon said valve, and that pressure is overcome by between five and six pounds stress upon the bellows plus about three pounds stress upon the bellows 31, when said pump 11 is in operation; the latter stress being imposed by the pressure of the atmosphere upon the plunger plate 33 when the water is partially exhausted from the bellows 31 by the suction of the pump.

However, itis to be understood that the respective stresses of said spring and bellows may be varied and the stresses upon said bellows be otherwise imposed. For instance, said bellows 31 may be subjected to internal pressure suiiicient to overcome or counter-` balance the internal pressure in the bellows 30 to permit the valve 5 to beclosed b y its spring 19, or said spring may be omitted and said valve positively opened and shut respectively by internal pressure in said bellows 30 and 31.
